CHAIR-SLEEPER AND TIE FOR RAILS.

SPECIFICATION formingpart of Letters Patent No. 494,074, dated March 21,1893.

Application filed December 6,1892. Serial No. 454,257. (No model.)

To all whom it may concern.-

Be it known that I, WYBRANTs GEORGE OLPHERTS, a citizen of England,residing at 38 Ebury Street, Pimlico, London, England, have invented anew or Improved Chair, Sleeper, and Tie for Rails, of which thefollowing is a specification.

My invention relates to a construction of chair sleeper and tie forrails so arranged that the rail is firmly supported under the shouldersof its upper head without any bearing of its lower head on the chair,and that the same key serves to hold the tie bar in position and also toset up the jaw, as I shall describe referring to the accompanyingdrawings.

Figure l'is a longitudinal section of a chair sleeper according to myinvention, the section being taken on the line X X of Fig. 2 which is aplan.

The base A, which is a little dished underneath, is cast with a crossrib B on its lower side, and with a jaw C and two longitudinal ribs D Don its upper side. It has also a square shouldered projection E, whichhas the same width as the tie bar F has thickness, standing up in themiddle and fitting into a notch of the tie bar. Between the ribs D D ajaw G can slide, and through the ribs D D and the back rib of the jaw Gpasses a cross key K by driving which the jaw G is set up so that therail R is clamped between it and the stationary jaw 0. Both the jaws Gand G are strengthened by internal ribs 0 and g and by external ribs 0'and g. The key by holding down the tie bar F keeps its notch engaged onthe projection E and thereby prevents the bar from moving lengthwise,and it is kept in position laterally by passing through slots of thechairs 0 and G and invention and the best means I know of carrying thesame into practical effect, I claim- A chair sleeper for rails,consisting of a base plate cast with a fixed jaw and with twolongitudinal ribs between which asliding jaw is set up by a key, bothjaws being so formed as to clamp the web of the rail immediately underthe head the shoulders of which rest on the jaws, in combination with atie bar having anotch in its edge held engaged with a projection on thebase plate by the key which sets up the jaw, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 23d day of November, A. D.1892.
